OTIS R. HINCHER, OF SEATTLE, WASHINGTON, AND ALFRED J. MORRISON, OF MINNEAPOLIS, MINNESOTA.

PAPER-BOX MACHINE.

To all whom it may concern:

Be it known that we, OTIS R. HINCHER and ALFRED J. Morrison, citizens of the United States, residing at Seattle, in the county of King and State of Washington, and Minneapolis, county of Hennepin, and State of Minnesota, respectively, have invented certain new and useful Improvements in Paper-Box Machines, of which the following is a specification.

This invention relates to paper-boX making machines; and its object is the provision of improved means for attaching bottoms or tops to boX-bodies or the covers thereof. 7

The invention consists in the novel construction and combination of devices, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a front elevational view of a machine em bodying our invention. Fig. 2 is a vertical Fig. 3 is an end elevation, viewed from the right hand side of Fig. 1. Fig. 1 is a fragmentary front elevation of the machine with parts thereof represented in different positions from where they are illustrated in Fig. 1. Fig. 5 is a cross sectional view through 55 of Fig. 1. Fig. 6 is a perspective view of the machine platen, with attachments thereof.

The reference numeral 1 designates the machine frame provided with bearings for a driving shaft 2 which, as shown, is arranged loi'igitudinally with respect to the frame. Mounted upon said shaft is a power-driven pulley 3. This pulley is loose upon the shaft and'may be coupled there with through the medium of a suitable clutch, desirably of the frictional type and whereof 4 designates one of the elements. For actuating the clutch there is provided a rod 5 disposed to be parallel with the shaft 2 which is supported in frame brackets 6 and carries at one end a shifter 7 which engages in a peripheral groove 4: of the boss of said clutch-element. A treadle-lever 8 is fulcrumed by a pin 9 to ears 10 provided for the frame and above the rod 5. Upon said lever is an offset lug 12 which with the main portion of the lever are apertured to receive the trunnions 13 of a sleeve 14 wherethrough the rod 5 extends.

15 are set collars upon the shifter-rod which are spaced from the said sleeve to Specification of Letters Patent.

accommodate intermediately disposed helical cushioning springs 16. Arranged transversely to the frame is a cam shaft 17 receiving rotary motion from said driving shaft while the latter is operative. For such power transmission we desirably employ worm and tooth gears 18 and 19 upon the respective shafts 2 and 17. A cam, 20, see Figs. 1 and 3, which will hereinafter be termed the controller-cam, is provided on the cam-shaft and coacts with a roll 21 which is carried by an arm 22 of the lever 8. Said controller-cam has a portion of its periphery concentric to its axis of rotation and also has a reentrant portion 20. A spring 24 connected with the lever-arm 22 and a rigid support to the rear of the machine frame serves to tilt the lever 8 such that the roll 21 thereof will bear against the periphery of the controlling-cam. Thus when the roll is tracking the concentric portion of the cam, the lever is maintained in condition to cause the shifting of rod 5 to effect the operative engagement of the driving pulley 3 with the shaft 2 and whence motion is derived to rotate the cam-shaft. hen the roll enters the depression 20 of the controlling-cam said coupling is disengaged with a consequent interruption to the operative parts of the entire machine. This cessation of motion occurs once in each cycle of operation unless, through the instrumentality of the treadle arm 11 of the lever 8 the operator prevents the roll entering said cam-depression.

Included in the machine frame is a support for a platen 25 and may consist of rigid bridge-members 26 which are provided with apertures to receive posts 27 which are fixedly connected to and depend from the platen, as shown in Fig. 2. About each post and between said platen and said support is a coil spring 28 whose function is to yieldingly sustain the platen in its uppermost position as determined by the adjustment of nuts 29 at the screw threaded lower ends of the posts.

In operation a stack of covering papers A are placed upon said platen and are kept in vertical alinement and in proper horizontal location by means of guide-elements 30 which are carried bv the platen, see Figs. 1 and 6. These guide-elements are severally connected to or formed integral with springplates 31 which have apertured lugs 32 to receive screws 33 for adjustably attaching the same to the platen. Such guide elements are each formed to present a straight edge 34: at the bottom which is arranged perpendicular to the top face of the platen and above they flare outwardly, as at 35.

In proximity to the ends of the platen and secured thereto is a pair of superposed trackrails 36 which are desirably made horizontal,

or nearly so, above the platen and to the rear carrying a. roll at which, through the agency of a spring 15, is kept in peripheral contact with the carrier-actuating cam 16 mounted upon the cam-shaft 17. Disposed at a sufficient distance above said track-rails to afford a free passage for the carrier is a platform 47 which is rigidly supported by legs 18, or otherwise, from the frame. Said platform is arranged to hold a removable paste-pan 4L9.

50 is a roller having its axle 51 journaled in bearings 52 provided for the platform l7 and upon one of the axle ends is a pulley 53 which is driven by a belt 54, Figs. 1 and 3, from a driven pulley 55 upon the cam shaft. The roller 50 is partially submerged in paste contained in the pan 49 and when the roller is rotated in the direction indicated by the dart in Fig. 2, it conveys upon its circumference a supply of paste to a pasteapplying roller 56. In order, however, that superfluous paste may not thereby be delivered to the paste-applying roller and that the paste may be properly distributed over the surface of the conveying roller 50 prior to its delivery to said applying roller, we

1 utilize a pressure roller 57 to attain such arms of levers 58 are each connected by a spring 59 with an attachment 60 of the platform. The paste-applying roller 56 is arranged for reciprocatory movements to and from the front of the machine; to which ends the axle 61 of the roller has its ends journaled in slipper-blocks 62 which travel upon guide-rods 63 supported from the frame. The ends of the axle 61 protrude outside the respective slipper-blocks and serve for making connection by links 64 with arms 65 which extend upwardly from a rock-shaft 66 journaled in bearings provided at the rear of the frame. Projecting forwardly from said rock-shaft, see Fig. 2, is an arm 67 carrying a roll 68 which is caused by a spring 69, acting through the arm 67, to bear against the periphery of a cam 70 and whereby the reciprocatory movements of the paste-applying roller 56 are obtained.

In a part 1 of the frame which overhangs the platen is a guideway for a vertically movable head 71 made operative from said cam shaft through the medium of a cam 72 thereupon, and connecting mechanism. Such mechanism may comprise an oscillatory beam 73 fulcrumed by a pin 73 with the frame and connected by a link 74 with said head. From between said head 71 and said fulcrum pin, the beam 73 is operatively connected by a rod 75 with a vibratile arm 76 which is fulcrumed by a pin 7 6, Fig. 3, with the frame. Intermediately of its length the arm 76 carries a roll 77 which engages the cam 72 from the underside. A weight 95 is advantageously provided for the outer end of the beam 73 to more than counterbalance the opposing weights depending from the beam. spring, not shown, in the drawings, may be substituted for or provided to cooperate with the weight 95. The beforementioned head is adapted, as by the provision of a flanged lower end 71, for having detachably fastened therewith, as by screws 78, a form 79 of suitable size to fit within a cover or bodypart B of a box. For convenience the term box-body hereinafter employed is to be understood to mean either part of a box. The head is likewise equipped with gripping-devices capable of exercising a two-fold duty, namely, to retain a box-body upon said form as it approaches the platen, and to eject the box-body therefrom upon the upward movements of the head. As shown in Figs. 1, 2 and 4, the gripping devices consist of companion members 80 each formed of a bellcrank shape and respectively connected with the head by pivotal pins 80. These members are arranged such that there will be an arm 81 of each directed upwardly and their other arms 82 directed laterally.

Adjustably secured by nutted screws 83, or an equivalent, to the respective arms 82 are downwardly extending hooks 84 whose oflice is to grip or clasp the box-body when they are brought into contact therewith in the performance of their duty and whereupon the respective hook-bills 85 are re sistently pressed back to occupy the shapes in which represented in Fig. 1. But when the hooks are withdrawn, through the appropriate tilting of the members 80, the resilient power of the hooks in resuming their normal shapes, Fig. 4, will effect the stripping of said form. The arms 81 of said companion members are constructed to have their outer edges provided with checks which slope outwardly from the upper extremities, or points 87 with depressions 88 therebelow. The members 80 are also characterized by having the upper ends of the arms 81 inclined forwardly, as shown in Fig. 2.

89 is a contractile spring representing the members 80 below their pivotal connections 80 and acting to retain the members in their normal positions, (Fig. 1). Secured near their outer ends to the frame part 1 is a pair of spring metal plates 90 whose inner ends, Fig. 5, are offset to allow the members 80 to pass downwardly therebehind in a corresponding movement of the head, but by reason of the upper ends of the members 80 being inclined forward, as previously stated, their points 87 will direct the members to have their cheeks 86 pass to the front of the plates 90 when ascending. The cheeks 86 will thus encounter studs 91 which protrude forwardly from the plates 90 and thereby cause the members 79 to be swerved outwardly, as will be understood from an inspection of Fig. 4. During the ascending movement of the head, the members are aifectechas explained, to withdraw the hooks from the box body. Then the elevation of the head is such as to present the depressions 88 to the plates 90, the latter will spring forward through the cavities and thus allow the members 80 to be in position to pass again to the rear of the plates in the following downward movement of the head.

In operation, the box-body B is placed by the operator upon the form 79 and engaged therewith by the hook-members 84L. applying foot-pressure to the treadle bar 11 the shifter rod 5 is influenced to cause the clutch element 4 engaging the driving shaft 2 with the power-driven pulley 3 resulting in the cam-shaft 17 being rotated through the medium of the geared connections 18 and 19. The paste-applying roller 56 is supplied with a coating of paste from the paste-pan 41-9 by means of the rotating roller 50. The cam in turning with its shaft allows the dipping of the arm 6'? and likewise allows the spring 69 to exercise its power to cause the rock-shaft 66 tilting the arms 65 to thrust the roller 56 forwardly and apply a layer of paste to the underside of the box-body B. The return of the roller 56 into juxtaposed position with the roller 50 is then accomplished by the spring 69. The cam 72 now asserts itself to draw the head 71 downwardly and press the box-body to which the paste has been applied against the paper at the top of the stack A and with a force capable of overcoming the power of the springs 28 which yieldingly uphold the platen 25. This relative power of the springs coiiperates with the positive opposing force exerted through the head and affords ample pressure to cause the adher ence of a paper to the box-body.

By the continued rotation of the cam 72 the weight 95 is allowed to operate to elevate the head. In the course of such head movement the members 80 are, as previously explained, influenced to release the box-body and cause it to be cast down upon the carrier 37 which, priorly, has been moved through the operation of the cam H into the position in which it is illustrated in Fig. 2. The continuance of the action of this cam permits the carrier being withdrawn by the spring 45 from below the head and into the position whereat it is shown in Fig. 3 to remove the work. This completes a cycle of operation and while the treadle arm 11 is held in its depressed position by the operators foot, to thereby maintain the clutch devices in couple, the machine will continue operative. It may be said that the guide-elements 30 are spread asunder by the descending head engaging the sloping faces 35 thereof to allow the box body coming into contact with the stack of papers.
